Speed sensor

Fantastic indian summer in Luxembourg... Lots of km done since Friday afternoon, and therefore, less work done on the car. 

A buddy in the french forum sevener.fr asked me how to mount the speed sensor for the Stack odometer. Here is a very simple method, a small aluminium piece fixed with the cycle wing bracket. This sensor is magnetic and counts the wheel nuts flying by (4 in this case). When setting up, the Stack asks for the wheel circumference and the number of events (bolts) per revolution, the electronics in the Stack can then calculate the speed the car is driving.

Cheers.
